Question SSD wear (read rate), no health %?

[ditrate]

Apacer AS340x -120gb (70 TBW)
There is no health %, so I don't know how much is left. Approximately I used 2-3%? Thanks

Is there some specific reason you are concerned?
That has a very low power on count and power on hours.

I using it only for torrents and HDD managing. Just wondering, should I be concerning?

My SSDs dont show a % either, its normal for that suite.

^ Apart from what my colleague above has said, the drive is also exhibiting good health courtesy of Crystal Disk. If you're experiencing slow downs on your SSD, it could for another reason. As far as the drive's health is concerned, you're in good hands.

Thanks, you good people!

The Average Erase Count is 0x47 (= 71 decimal). QLC NAND has an endurance rating of around 1000 P/E cycles.

Therefore, if this SSD is using QLC NAND, it has used up 7.1% of its endurance after 917 hours. At this rate it will be at 68% after 1 year, and 0% after 1.5 years.

TLC NAND has better endurance.

Would this drive work fine at least until the end of this year?

Would this drive work fine the until the end of this year. Or I immediately need a replacement?

An SSD can fail at any time without warning. Nobody knows the answer to your question.

Understand. But I asking theoretically, all variables consider?

The only theoretical way to calculate wear is the capacity multiplied by how many times the cells can be rewritten. For TLC flash memory, the range is 500-1,000 cycles. So for a 1TB drive, assuming perfect wear leveling, you're looking at 500 TB to 1000 TB of total writes before the thing wears out.

On the vendor official website it’s said - 70 TBW and 1,500,000 MTBF, for a 120 gb ver.

The WAF (write amplification factor) for the OP's SSD appears to be about 4:1. That is, the total writes to NAND is about 4 times the total writes from host to SSD via SATA.

There is literally no way to know.
It could die tomorrow, or last until 2040.
